Red Hardness

,

In this opening video I discuss future topics and also do a demonstration on how the metallurgical term red hardness relates to carbon and high speed steels.

Dial Carriage Stop

There has been a lot of interest in the dial carriage stop on my lathe, so I made this video to show what it is, how it’s made and how it works.

Parting on the Lathe

Parting is one of the most misunderstood machining operations on the lathe. This video covers how to properly grind the tool, how to set the tool so it is rigid and properly aligned, and lubrication. Following these basic guidelines can greatly reduce the amount of heartburn associated with the parting […]

Center Drills and Center Drilling

This video covers various types of center drills and their applications, how to properly use them and pitfalls to watch out for.

Facing on the Lathe

The first in a series of videos on the most basic machining operations. This one covers how to face the end of a part or shoulder using a tool using a tool ground in the video “Grinding Turning and Facing Tools for the Lathe”.

Cutting Speed and RPM on the Lathe and Mill

,

Proper rpm on the lathe and mill increases tool life and productivity. This lesson discusses how to determine the proper cutting speed for various metals and how to convert that cutting speed to the correct rpm for the tool or part.

How to Wind a Coil Spring on the Metal Lathe

A step by step procedure to wind a coil spring on the metal lathe that covers safety as well as how to make the required specialized tooling.

Cutting an Internal Thread on the Atlas Lathe, Part One – Setting up the Change Gears

This first of a three part series on cutting an internal thread on the Atlas lathe, covers setting up the change gears to cut a twelve pitch thread. I discuss how to read the chart and to properly set the backlash in the gears.

Cutting an Internal Thread on the Atlas Lathe, Part Two – Setting Up the Tool

This second of a three part series on cutting an internal thread on the Atlas lathe covers the details of setting up the tool. I show how to position the compound, boring bar and tool, how to zero the dials, and how to take the first cut.

Cutting an Internal Thread on the Atlas Lathe, Part Three – Cutting the Thread

This last of a three part series on cutting an internal thread on the Atlas lathe covers the actual cutting of the thread. I show how to use the cross slide to retract the tool, how to reduce chatter, and how to measure the diameter of the thread.

Taking the Mystery out of the Threading Dial

A practical demonstration of the “why” behind the threading dial.

Safety First Video #1, How to Safely Use a File on the Lathe

,

In this first in a series of short safety videos, I discuss how to safely use a file on the lathe.

Using a Corner Rounding End Mill on the Lathe

Corner rounding end mills aren’t just for the mill, they work just as well on the lathe and will save you the trouble of grinding a form tool.

Thread Cutting on the Lathe, Part One

The first in a series on how to cut threads on the lathe, this episode explores the information required to grind a V-thread cutting tool. It covers why high speed steel is the best choice for the hobby machinist, and the geometry of a lathe threading tool.

Thread Cutting on the Lathe, Part Two – Calculating the Flat Width and Helix Angle

In this episode of thread cutting on the lathe we calculate the width of the flat and discuss three different ways to calculate the helix angle.

Thread Cutting on the Lathe, Part Three – Grinding the Tool

,

In this episode of thread cutting on the lathe we calculate the width of the flat and discuss three different ways to calculate the helix angle.

Thread Cutting on the Lathe, Part Four – Setting up the Lathe and Cutting the Thread

In this final installment of my Thread Cutting on the Lathe series, we’ll use the tool that we ground in earlier episodes to actually cut a thread. Topics covered are setting up the lathe, cutting the thread and measuring the thread using the three wire method.
